The role of electric heat tracing medium pressure sensitive tape and aluminum foil tape

Electric heating is an effective pipe insulation and freeze protection solution that has been widely used. Electric heat tracing temperature gradient is small, thermal stability time is long, suitable for long-term use, its working principle is to emit a certain amount of heat through the heat tracing medium, through direct or indirect heat exchange to supplement the loss of the heat tracing pipeline, in order to achieve the normal work requirements of heating, heat preservation or antifreeze.

The installation process of electric heat tracing system involves many accessories, in addition to two-way/three-way junction boxes, explosion-proof temperature controllers, explosion-proof power junction boxes, and commonly used special tape for electric heat tracing. Specifically, "tapes" are divided into heat-resistant pressure-sensitive tapes and aluminum foil tapes.

Pressure-sensitive tape is used to fix electric heat tracing and pipelines, can withstand temperatures up to 200 °C, aluminum foil tape can be used in electric cable systems to fix electric tropics, fixed thermostat capillaries and temperature probes, or aluminum foil tape for auxiliary fixation of flexible hot plates. In addition to facilitating the installation and fixation of electric heating products, in some electric heating systems, the limitations of the outer sheath material of the electric heat trace, due to the different materials of the pipeline, etc., will more or less uneven heat transfer. It will cause concentrated heat accumulation at a certain point in the pipeline, especially at the discount of the installation of the electric trace. How to solve such a problem, it is necessary to use aluminum foil tape, which can increase the heating area of the pipeline, so as to ensure the effect of electric heating of the pipeline.

The biggest difference between the two is that the pressure-sensitive tape is fixed laterally, while the aluminum foil tape is fixed along the heat trace and firmly attached to the pipe.

Pressure-sensitive tape and aluminum foil tape is an important part of the electric heating system, indispensable, in the installation of the user which is missing, the electric heat tracing insulation effect will be greatly reduced, so when using the electric heating system need to contact the electric heating manufacturer, and the electric heating manufacturer is equipped with a complete set of electric heating system.
